D Shaped Silicone Rubber Strip
Custom D Shaped Silicone Rubber Strip Supplier
D shaped silicone rubber strip is widely used when a project needs a soft compression seal with a rounded contact surface. The D profile helps absorb pressure, reduce vibration, and seal uneven gaps more effectively than many flat strip designs.
At Suconvey, we manufacture custom D shaped silicone rubber strips for industrial sealing, equipment doors, access panels, cabinets, glazing systems, vehicle components, and other custom assemblies. We can adjust the profile size, hardness, color, and supply form based on your drawing, sample, or application details.

The D shape is popular because it compresses well while keeping a stable profile. When installed on doors, covers, housings, or panels, the rounded top section helps create a more reliable contact area. This makes it useful for sealing against dust, air, splash, heat, and vibration.
Silicone is also a strong material choice for applications that face temperature change, outdoor exposure, or long service cycles. On the current Suconvey page, the strip is described as flexible, weatherproof, waterproof, and suitable for a wide range of uses including windows, doors, showers, cars, and boats.

These applications align with the current page, which lists high-temperature seals for heating equipment, as well as doors, windows, freezers, showers, pumps, and automotive-related uses.
Material and Performance Considerations
When selecting a D shaped silicone strip, the most important point is not just the outside shape. You also need to confirm the compression requirement, the gap size, the working temperature, and whether the strip needs to resist water, chemicals, or long outdoor exposure.
We list a general material range including specific gravity of 0.9–1.3 g/cm³, hardness of 20–90 Shore A, working temperature from -60°C to 350°C, elongation of 300–650%, and deformation rate of ≤9%. These ranges are useful as a starting reference, but the final grade should still match the real service condition.

Standard strips can work for simple jobs, but many industrial buyers need a profile that matches a specific groove, gap, or compression target. Custom D shaped silicone strip can improve fit, reduce assembly issues, and provide more stable long-term sealing.
Suconvey’s silicone seal strip is continuous extrusion, tight tolerances, and custom profile production. That is important for buyers who care about repeatability between sample approval and mass production.

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone strips are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.
Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test strips can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.
After-Arrival Support
If any damage or discrepancies are discovered during unloading or inspection, customers may contact us within 7 days with photos and batch information. Our team will respond promptly to assess the situation and provide a reasonable solution.

Frequently Asked Questions
If your question is not listed, please contact us.
Before ordering, it helps to confirm:
- The gap size to be sealed
- The compression level required in use
- The installation method
- Whether adhesive backing is needed
- The operating temperature range
- Whether the strip is exposed to water, weather, steam, or chemicals
- Whether you need rolls, cut lengths, or a custom profile drawing
A good D shaped silicone strip should compress easily, recover after pressure, and keep a stable sealing line during repeated use.
D shaped profile usually gives better compression performance because the rounded section can absorb pressure more evenly. It is often a better choice when the seal needs rebound, cushioning, and more consistent contact against another surface.
Yes. Custom D shaped silicone rubber strips can be produced according to drawings, profile dimensions, samples, or application details. This helps match the strip to the gap size, compression requirement, and installation method of the actual project.
Yes. Food grade, medical grade, and commercial grade options are available. The final material grade should still be selected according to the actual application environment and compliance requirement.
